It is well known that Snejana’s favourite brand is Balmain, her favourite clothes on and off the runway. So it’s not difficult to imagine that this is probably one of her favourite jobs in her career! Snejana is the face of Pierre Balmain, the new more affordable line for the brand. These are just preliminary images, but I think that the black and white picture is a campaign since it is very similar to the mainline campaign with Daria, and the others are a look book.
Edit: models.com confirm this as Pierre Balmain S/S 2012 campaign! Photographer is Giampaolo Sgura.
